ABB RVC10-5A Power Factor Controller

The ABB RVC10-5A power factor controller is designed for automatic capacitor bank systems to monitor reactive power and drive capacitor switching for power factor correction, providing precise control over when capacitors engage to maintain the target power factor in real time. Typically installed in industrial electrical panels, MCC rooms, and facility power distribution systems that serve motors, compressors, and variable loads, it is used by electrical maintenance teams, engineers, and system integrators to implement power quality improvements, perform capacitor bank retrofits, support panel upgrades, and ensure compliance with utility power factor requirements. Key specifications include MPN RVC10-5A with Alternate Part Number RVC105A, 5-step capacitor bank control, measurement voltage 90–550 VAC, measurement current 5 A via external CT, relay outputs for capacitor switching, a digital LCD display, automatic power factor regulation, panel-mount installation, and operation at 50/60 Hz. Common replacements listed for this model are ABB RVC12-5A, ABB RVT-12, and Schneider Electric Varlogic RVC, reflecting its role in retrofit and modernization projects across industrial power systems.
